Tear Strength Test Methods and Acceptable Limits
Tear Strength is verified through ISO 13937-2 trouser tear. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
ISO 13937-2 trouser tear defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Tear Strength normally sit around above 10 N typical in mainstream production. Note ISO 13937-2 trouser tear on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; above 10 N typical is only meaningful for similar fabrics. Record elastane content alongside Tear Strength, because blends shift the measured value. A result outside above 10 N typical usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write above 10 N typical with a stated tolerance, then verify against ISO 13937-2 trouser tear. Keeping reference values for Tear Strength lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13937-2 trouser tear, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Tear Strength normally sit around above 10 N typical in mainstream production. Note ISO 13937-2 trouser tear on the tech pack so nobody tests against an older revision.
Documentation
Record the standard revision on every report, because older versions can differ from current practice. Record elastane content alongside Tear Strength, because blends shift the measured value. A result outside above 10 N typical usually points to process drift rather than to the fibre itself.
